Procurement Notes

This component is listed as discontinued by the manufacturer. Verification of availability through authorized distributors or surplus channels is required. Ensure compatibility with existing system designs before procurement due to end-of-life status.

Selection Notes

Select this part for legacy SAS/SATA designs requiring a fixed 150MHz LVDS clock. Verify that the 8-SOIC package fits the PCB layout constraints. Confirm that the 2.375V-2.625V supply voltage aligns with the system power architecture.

Part Context

Part of the Renesas FemtoClock® series, which specializes in low-jitter silicon timing solutions. This specific model targets high-reliability storage interconnects, offering better frequency stability compared to SAW oscillators through its PLL-based generation method.

Replacement Considerations

As the part is discontinued, verify if newer FemtoClock models support equivalent frequencies and LVDS outputs. Check for pin-compatible alternatives if board re-splicing is not feasible.
